JACOB BERN'STEIN, OF OMAHA, NEBRASKA.

SOOT COLLECTOR.

' Application filed May 20,

T 0 all whom it may concern:

Be it known that I, JACOB Bnnnsrnm, a citizen of the United States, anda resident of Omaha, in the county of Douglas and State of Nebraska,have invented a new and useful Improvement in Soot Collectors, of whichthe following is a full, clear, and exact description.

My invention relates to soot collecting devices, and it consists in thecombinations, constructions and arrangements herein described andclaimed.

An object of my invention is to provide a soot collector that is adaptedfor use in drawing soot from the smoke outlet of a heating apparatus andfor conducting the soot to a desired place, as for instance, to a bag orother receptacle.

A further object of my invention is to provide a device of the characterdescribed that is capable of being moved. readily from place to placefor use in turn at widely separated points.

A further object of my invention is to provide a device of the characterdescribed that is relatively simple in construction and operation andnot likely to get out of order easily.

A further object of my invention is to provide a soot collector that isthoroughly effective for the purpose intended and can be operated at arelatively low cost.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointedoutin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which- Figure 1 is a side elevation of thedevice, portions thereof being broken away and other portions beingshown in section.

Figure 2 is an enlarged plan view of the device, portions thereof beingbroken away and other portions being shown in section,

Figure 3 is a sectional detail of a frugmentary portion of the device,and

Figure 4 is a detail of another fragmentary portion of the device.

In carrying out my invention, I make use of a vehicle which may be ofany suitable type of construction and, in the drawings, is indicatedgenerally at 1. Mounted upon the vehicle 1 is a power device 2 ofordinary construction. I prefer to use an internal combustion engine ofan ordinary and well known type as the power mechanism in theSpecification of Letters Patent.

device. The internal combustion engine is secured by bolts 3 or otherfastening means to the body of the vehicle. A fan f: of the blower typeis supported by a base that is likewise secured to the vehicle body bysuitable fastening means, such as the bolts (3. The fan at is driven bya belt an d pulley connection indicated generally at T with the internalcombustion engine 2. An intake or suction conduit 8 communicativelyconnects at one end with the fan 4 adjacent to the axis of the latt rand is adapted for connection at its other end with a flexible tube 9, Adelivery tube 10 leads from the periphery of the fan 4 and branches at11 to provide two branch delivery tubes 12 and 13 respectively. Thebranch delivery tube 12 opens into a soot receiving member 14 throughthe side wall of the latter adjacent to its upper end, as best seen inFigure 3. The branch tube 13 likewise communicates with a similar sootreceiving member 15 through the side wall of the latter adjacent to itsupper end.

The soot receiving members 14 and 15 are substantially identical withone another in essential respects and each has the form of an invertedcone closed at its upper end except for a central opening 16 having atubular extension 17 depending therefrom. Each soot collecting cone isprovided with a discharge orifice 18 at its lower end and a suitablereceptacle 19 which may be a bag, is removably secured at 20 at thelower end of each cone to receive the soot passing through the dischargeorifice 18. Ar-

ranged to enter the opening 16 to depend.

within each cone is the tubular portion 21 of a header 22 which isenlarged exteriorly of the cone so that the walls thereof are inclinedoutwardly, as shown. The header 22 is provided with an upper end wallwhich has a central opening 2%. An upstanding tubular member from theopening 24: is integral with the wall 23. An intake tube 26 is arrangedto enter the tubu lar member 25 to depend through the opening 24 intothe header 22 to a point slightly below the level of the upper end ofthe cone. A screen supporting frame 27 has a tubular stem 28 disposed inthe upper end of the intake tube 26 and supported by the latter. Thescreen supporting frame 27 is covered by a screen 28 of suitable meshand is provided with radially extending brace rods 29. Certain of thebrace rods 29 connect with the tubular stem 28, while 'others are stayedby a tie member 30. The stem 28 is fashioned with an inwardly extendinglug 31 constituting a bearing for a crank 32. A brush 33 is carried bythe crank arm 32 in position to engage the inner wall of the screen 28when the crank is rotated. The screen 28 may consist of a suitablefabric, preferably a heavy cloth, and be renewed when worn or damaged inservice. A return conduit 3 is provided for each head 22 and connectswith the latter adjacent to its upper end. The conduits 3% unite at 35to provide a main return conduit 36 that communicates with the fan iadjacent to the axis of the latter.

From the foregoing description of the various parts of the device,theoperation thereof may be readily understood. The flexible tube 9 maybe formed of sections to provide any suitable length and the end thereofis connected to the smoke outlet of the heating apparatus from which thesoot is to be drawn. The fan at is then operated and soot is drawnthrough the intake conduit 8 and blown therefrom through the deliverytube 10 and, through the branch delivery tubes 12 and 13 into the sootreceiving cones 14 and 15. It is to be observed that the air with theentrained soot forced along the delivery tube 10 enters each Conethrough its side wall at the upper end of the latter and the mingledsoot and air will pass in spiral convolutions of decreasing diameterdownwardly through the soot receiving cone, thereby creating a partialvacuum at the center of each cone. The soot will be discharged throughthe discharge orifice S into the receptacles 19. The return tube 36alsocommunicates with the fan 4 adjacent to the axis of the latterrand theoperation of the fan will cause a suction on the head 22 which will tendto draw air upwardly from the center of the cone, thereby drawingpractically all air from the cone into the branch return tubes 3d, whilepractically all of the soot passes into the receptacles 1.). In theevent any of the finer soot passes up ardly with the air drawn into thetubes it may pass along the latter to the fan f and he forced throughthe delivery tube 10 again. Any soot entering the tubular intake member26 will be caught by the screen 23 and may be dislodged therefrom byoperating the crank 32 either before or after the screen frame has beenremoved from the header 22. It will thus be obvious that practically allthe soot drawn from the flue is collected. The device may be movedreadily from place to place and is ready for operation instantly. Thesoot receiving cones la and 15 are supported on the vehicle body bysuitable fastening means, such as the brackets 37.

I claim: 1. In a device of the character described,
